  It adds up to 4! Thiophenes and thiazoles can be arylated in the 4‐ rather than the expected 5‐position in a new CH functionalization reaction (see scheme; TEMPO: 2,2,6,6‐tetramethylpiperidine‐N‐oxyl). The boronic acid proved to be the key to achieving the otherwise difficult C4 selectivity. The method was applied to a concise synthesis of a key pharmacological structure with potential for treatment

  less‐reactive β position of thiophenes was previously inaccessible to direct functionalization. However, the β selectivity observed with the catalytic system PdCl2/POCH(CF3)2}3/Ag2CO3 in the arylation of thiophenes with iodoarenes (see scheme) is a remarkably general phenomenon applicable to unsubstituted, monosubstituted, and disubstituted thiophene derivatives, as well as thiophene‐containing fused aromatic

  Thieno[3,2-b]thiophenes (TT), having pare-substituted phenyl groups at C-3, have been synthesized through a ring closure reaction, using P4S10, in moderate to high yields. Their absorbance studies displayed that the TT, having nitrophenyl group had the most red shift absorbance at 365 nm, which also showed the lowest optical band gap of 2.92 eV; the rest of the TTs had the absorbance between 300 and 302 nm. Cyclic voltammetry studies indicated that while all the TTs had the oxidation potentials above 1.0 V, the TT with dimethylaminophenyl group had the lowest oxidation potential of 1.33 V. The rest had the oxidation potentials between 1.6 and 1.99 V. The TTs were both electropolymerized and copolymerized with thiophene through Suzuki coupling reaction. Electropolymerized polymers indicated that while the polymer having strong electron donating dimethylaminophenyl group had the lowest oxidation potential of 0.97 V, the rest of the polymers displayed the potentials between 1.09 and 1.39 V. Their electronic band gaps varied between 1.86 and 2.46 eV. The CV-UV studies of the polymers, electro-deposited on ITO, showed absorbance maxima between 431 and 468 nm, and the lowest optical band gap was observed with the polymer having methoxyphenyl group (1.99 eV). The rest of the polymers had the optical band gaps between 2.05 and 2.19 eV. Regarding the copolymers, the one with methoxyphenyl group had the lowest oxidation potential of 0.75 V. They displayed absorption and emission maxima between 325 and 445 and 454-564 nm, respectively. Their optical and electronic band gaps varied between 2.0 and 2.5 eV. As the copolymer having strong electron donating methoxyphenyl group had the highest quantum yield, 0.64 eV, the one with strong electron withdrawing nitrophenyl group had the lowest quantum yield of 0.003 eV.
